Before adding the directly controlled resets support it's reasonable to move the existing resets control functionality into a dedicated object for the sake of the CCU dividers clock driver simplification. After the new functionality was added clk-ccu-div.c would have got to a mixture of the weakly dependent clocks and resets methods. Splitting the methods up into the two objects will make the code easier to read and maintain. It shall also improve the code scalability (though hopefully we won't need this part that much in the future). The reset control functionality is now implemented in the framework of a single unit since splitting it up doesn't make much sense due to relatively simple reset operations. The ccu-rst.c has been designed to be looking like ccu-div.c or ccu-pll.c with two globally available methods for the sake of the code unification and better code readability. This commit doesn't provide any change in the CCU reset implementation semantics. As before the driver will support the trigger-like CCU resets only, which are responsible for the AXI-bus, APB-bus and SATA-ref blocks reset. The assert/de-assert-capable reset controls support will be added in the next commit. Note the CCU Clock dividers and resets functionality split up was possible due to not having any side-effects (at least we didn't found ones) of the regmap-based concurrent access of the common CCU dividers/reset CSRs.
